RADCAT is a revitalized special
project now being conducted
jointly by NICAP &
Project 1947 with the help and
cooperation of the original compiler of RADCAT, Martin Shough, to create a comprehensive listing
of radar cases with detailed
documentation from all
previous catalogues, including
UFOCAT and original
RADCAT.

Feb. 12, 1962; Winnemucca AFB, Nevada
At 8:06 a.m. local time, radar of the 658 Radar Squadron painted one
large target considered to be out of the ordinary because of the height
and range. Object appeared at 74,000 feet and disappeared in excess of
96,000 feet. The object was on the scope for 5 minutes. Observer was
S/Sgt F. Grover, Crew Chief 658th RS, with 11 years of radar
experience. Radar type was an FPS-6B. (Dan Wilson)

Note:

The AN/FPS-6 radar, developed at RADC, was the first
long-range height finder radar employed at all Semi-Automatic Ground
Environment (SAGE) locations. This system had a maximum range of 200
nautical miles and a height-finding capacity of 75,000 feet within an
angle limit of minus 2 to plus 32 degrees. The AN/FPS-90 is a modified
AN/FPS-6B.
